对NSDictionaries的NSArray排序忽略大小写

Question

我正在使用以下代码对NSDiction的NSArray进行排序

NSArray *getIndexArray = [nicknamesCombinedArray copy];

            NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"MANUFACTURER"  ascending:YES];
            NSDictionary *sortedGetIndexArray = [getIndexArray sortedArrayUsingDescriptors:[NSArray arrayWithObjects:descriptor,nil]];

唯一的问题是当它排序时，如果这个词都是CAPS，那么就像这样排序

JESS
Jack
Jelly
Job

我希望它在哪里

Jack
Jelly
JESS
Job

试试这个代码..

NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"MANUFACTURER"  ascending:YES  selector:@selector(localizedCaseInsensitiveCompare:)];
